As it is shown in figure 5, distinguish sandwiched between the back side 40b and the surface of each solenoid 4b, 5b, 6b of intermediate wall 40 Elastic member 70.Elastic component 70 is the leaf spring being formed as V-shape under side-looking is observed, by each solenoid 4b, 5b, 6b Compress to matrix 10, and absorb the vibration of each solenoid 4b, 5b, 6b.

As it is shown on figure 3, four the connection terminal 8a arranged on the second pressure transducer 8 are through first sensor opening Portion 44, and electrically connected with sensor side terminal 61c, 63b, 64b, 65b by methods such as welding.

Four the connection terminal 7a arranged on the first pressure transducer 7 are through the second sensor peristome 45, and lead to Cross the methods such as welding to electrically connect with sensor side terminal 61b, 62b, 64c, 66b.

In above such main hydraulic cylinder unit A1, as shown in Figure 8, by arranging coil sides on intermediate wall 40 Bus 51～54 each other along coil sides delamination area S1 of table back of the body direction layering and by sensor side bus each other 61～66 along table Sensor side delamination area S2 of back of the body direction layering～S4, thus bus is assembled.And, by arranging on intermediate wall 40 The region that coil sides bus group 50 and sensor side bus group 60 are layered along table back of the body direction, thus by different types of bus 51 ～54,61～66 assemble.

Therefore, in housing 20, it is possible to reduce for housing bus 51～the space of 54,61～66, and improve bus 51 ～the degree of freedom of the process of 54,61～66, therefore, it is possible to make housing 20 miniaturization and lightweight.

Further, since for housing that the space of bus 51～54,61～66 is little and the process of bus 51～54,61～66 Degree of freedom is high, even if therefore 4,5,6 and two pressure transducers 7,8 of three stop valves being arranged in housing 20 compactly, Configuration bus 51～the space of 54,61～66 is can also ensure that in housing 20.

Further, since by coil sides delamination area S1 and sensor side delamination area S2～S4 along the width of intermediate wall 40 Direction is in staggered configuration, therefore, it is possible to prevent the delamination area of bus 51～54,61～66 from carrying on the back the situation becoming big on direction at table.

It addition, as shown in Figure 6, be housed in housing 20 three stop valves 4,5,6 are configured to, midfeather 40 On the 40a of surface, constitute isoceles triangle by line segment L1, L2, the L3 linked by the shaft core position of three electromagnetic valves 4a, 5a, 6a Shape, it is possible to be housed in housing 20 three stop valves 4,5,6 compactly.

The most in the present embodiment, by three corners configuration stop valves 4 in four corners of surrounding wall portion 30, 5,6, thus effectively utilize the space in housing 20.

It addition, the second pressure transducer 8 is arranged in the drift angle P1's of the isosceles triangle by line segment L1, L2, L3 composition On bisector L4.And, the second pressure transducer 8, on the surface 40a of intermediate wall 40, is arranged in by by three electromagnetic valves The region that line segment L1, L2, L5, L6 that the shaft core position of 4a, 5a, 6a and the shaft core position of the first pressure transducer 7 link surrounds Inner side, and be arranged in the outside in the region of the isosceles triangle shape surrounded by line segment L1, L2, L3.In this structure, it is possible to Compact for 4,5,6 and two pressure transducers 7,8 of three stop valves and balance are arranged in housing 20 well.

It addition, as shown in FIG. 11 and 12, in delamination area S1～S4, coil sides bus 51～54 is each other and sensor Side bus 61～66 is layered, even if at bus along table back of the body direction when staggering along the width of intermediate wall 40 each other In 51～54,61～66 regions being layered each other, it is also possible to by pushpin etc. by bus 51～54,61～66 from table back of the body side To sandwiching, the most in formation during partition portion 40, it is possible to bus 51～54,61～66 is positioned exactly.

It addition, as it is shown in figure 5, stop valve 4,5,6 is installed when staggering along table back of the body direction (with reference to Fig. 3) each other In intermediate wall 40, it is possible to improve the degree of freedom of the layout on the hydraulic pressure road being formed at matrix 10.

It addition, as it is shown in fig. 7, form recess 46,48 and protuberance 47 on the surface 40a of intermediate wall 40 and make midfeather The surface area in portion 40 increases, therefore, it is possible to improve the thermal diffusivity of intermediate wall 40.And, by forming recess at intermediate wall 40 46,48 and protuberance 47, it is possible to the wall thickness of suppression intermediate wall 40, and increase the intensity of intermediate wall 40.Therefore, it is possible to prevent heat The decline of the intensity of the housing 20 caused.

Further, since on the surface 40a in recess 46,48 and protuberance 47 wall formed between portion 40, therefore pass through midfeather The back side 40b (with reference to Fig. 5) in portion 40 can stably bear elastic component 70, and be prevented from because of from elastic component 70 by The situation that the intensity of pressure and intermediate wall 40 declines.

Further, since protuberance 47 is made up of the rib 47a radially formed, recess 46,48 is provided with radially landform The rib 48a become, therefore, it is possible to make effectively to disperse by pressure to what intermediate wall 40 acted on from elastic component 70.

Further, since recess 46,48 is avoided being embedded in the bus 51～54,61～66 of intermediate wall 40 and being formed, therefore The wall thickness of intermediate wall 40 can be suppressed.

It addition, intermediate wall 40, recess 46,48 and protuberance 47 are formed by resin material, therefore, it is possible to by recess 46,48 And protuberance 47 is integrally formed with intermediate wall 40.

This concludes the description of embodiments of the present invention, but the present invention is not defined to above-mentioned embodiment, without departing from it Can suitably change in the range of purport.

Such as, coil sides bus shown in Fig. 8 51～54 and the number of sensor side bus 61～66 or configuration not limit Fixed, suitably set according to number or the configuration of the electric component in housing 20.

It addition, in the present embodiment, 4,5,6 and two pressure transducers 7,8 of three stop valves are housed in housing 20 In, but its number or configuration do not limit.And, it is housed in the electric component in housing 20 and is not defined to stop valve and pressure Force transducer.For example, it is also possible to the substrate controlling electric component is housed in housing 20.

It addition, in the present embodiment, be provided with coil sides delamination area S1 and sensor side delamination area S2～S4 this Both sides but it also may the side in coil sides delamination area S1 and sensor side delamination area S2～S4 is set.Moreover, it is also possible to It is not provided with coil sides delamination area S1 and sensor side delamination area S2～S4.

It addition, in the present embodiment, as it is shown in fig. 7, on the surface 40a of intermediate wall 40, define recess 46,48 And these both sides of protuberance 47, but according to the intensity of intermediate wall 40 or the difference of thermal diffusivity, as long as forming recess and protuberance at least One side.And, recess and the shape of protuberance or configuration do not limit.Furthermore, it is also possible in the back side shape of intermediate wall 40 Become recess and protuberance.

It addition, in the present embodiment, the recess 46,47 of intermediate wall 40 and protuberance 47 by resin material with centre Wall portion 40 is integrally formed but it also may form recess and protuberance by metal material, and by mold formed to recess and protuberance in Partition portion 40.

It addition, in the present embodiment, illustrate and the vehicle brake fluid pressure device of the present invention is applicable to Fig. 1 institute The situation of the main hydraulic cylinder unit A1 of Vehicle brake system A shown, but the vehicle brake fluid that can be suitable for the present invention press-fits The device put does not limits, it is also possible to be applicable to such as perform the hydraulic control dress of ABS control, break away control or traction control etc. Put.
